Meter / Counter

Meter / Counter
Function description
The Meter / Counter function can be used as an hours run meter or as a pulse counter.
The pulse counter mode also allows litres (e.g. water consumption), energy (e.g. electrical
energy) or cubic metres (e.g. gas consumption) to be metered with the aid of input pulses.
Input variables
Enable
General enabling of the function (digital input signal ON/OFF)
Meter reset
Digital pulse input signal, ON/OFF, to reset the meter
Price / unit
A price per unit for yield calculations
Input 1 – 6
Digital input signal, ON/OFF (hours run meter) or pulse signals (pulse
counter)
➢ The meter reset is carried out by a digital ON pulse or manually in the parameter menu. It
will delete all meter readings, in other words also those from previous periods. The meter
will be blocked as long as this input variable is set to ON. The meter reset also works when
Enable = Off.
➢ Pulse signals may have up to 10 Hz at inputs 1-14 (50 ms pulse duration, 50 ms pause),
and up to 20 Hz at inputs 15 and 16 (25 ms pulse duration, 25 ms pause). The inputs 15
and 16 can therefore be used without restriction for S0 signals from meters/counters.
➢ Price / unit: Unit exceptions:
For the hours run meter, the unit is one hour (3600 seconds)
For the pulse counter / Energy unit, the unit is 0.1 kWh
Parameters for hours run meter
Mode
Available for selection: Hours run meter
Delete meter reading
Button for deleting all meter readings
➢ If more than one input is listed in the input variables, the hours will be metered as long as at
least one input is set to ON.
Parameters for pulse counter
Mode
Available for selection: Pulse counter
Unit
Divisor
Factor
Available for selection: Pulses, Litre, Energy, Cubic metre
Enter: number of pulses per unit
Enter: number of units per pulse
Input count direction 1 - 6
Define the counting direction for each pulse input
Available for selection: positive / negative
Delete meter reading
Button for deleting all meter readings
➢ In the pulse counter mode, all inputs are included in the count.
➢ With the Energy unit (kWh) one pulse equates to 0.1 kWh (if divisor and factor are 1).
➢ Count direction: The count direction can be defined for each input. Inputs can thus also
reduce the counter reading, and differential results can be produced. This also means that
the counter reading can have a negative value.
➢ If pulse signals arrive at different inputs simultaneously, every pulse will be counted
according to its count direction.
